All three charts declare a chart.link.dimension over one record set registered with ApexCharts.crossfilter({ id, records }). Clicking a slice or bar toggles that bucket: the clicked chart dims its other buckets, and every other chart re-aggregates over the filtered trades and animates to its new values. Selections combine (a chart never filters itself), so you always see what is still available. Reset filters clears everything. Needs the link feature.
